Bc it known that I, GEORGE A. honor, a., citizen of the United States,residin iin* the borough of Brooklyn, in the count oKings, in the cityand State of New Yer here 1nvented certain new and usefoi" imprese#ments in Looms for Weaving 'nlnisr Fahs ecicetion. This inventionrelates to the clss of looms for weaving tubular fabrics wherein theshuttie or shuttles are carried about the axis of the loom in an endlesspath lay-means within the tube formed by the Werps.

In the accom anying drawings, which illustrate en'rembo ment of theinvention, Figure 1 is en elevation showing tbe-warps lend web in place.of the up er part ofthe loomand Fig. 2* section o the reed, showing is sthe means .for

At (see Fig.2*) the arms each carry two grooved rollers 25, which embrace the innerrim of the reed. The reed cannot, of course, rotate against rotarymovement by the warps; but the arms 23 and 24 are carried around by theshaft 7 and impart to the reed a gyratory movement, the hi her roller ofthe pair 24 oint where the weft thread, aid by theshuttle, is beaten up.In 'Fig 2 this )oint is indicated by z. Above the reed an a shortdistance above the point z where the web W begins is a ring 26, mountsI5 ed loose on the main shaft inside of theweh.

This ring is a shaper to maintain the web at this point of tubular clindrical form, and

:.above it, also loose on t e central shaft, is a spreader,27,. adaptedto, flatten the tubullar ted 'for in Fig.

Mounted onand concentric with the reed .22@is a circular track 29, whichmay be called the "shuttle-racef' and along which the The shuttle and.its carrier now be specifically described with especial reference to`Figs. 8 and 9, the latter 4 f'sli'ow'iii the reed in section at line 1in Fig. "-8and t e shuttlein side elevation. In these views theshuttle-body has two outer rollers 30 to bear and rollalong-.thecircular race 29 and two inner rollers 31, which are inipnged l uponbythe arms of the'shuttle-carrier 2R.

It will of course be understood that in weavthe shuttle moves 'through ashed formed l inthe warps as it advances and that one set of warps isinterposed between the rollers 36 and the race 29, While the other setof warps is interposed between the rollers 31 and than the rollers 31 onthe shuttle in order that thelat ter may en tor a little between theformer, and thus enable the carrier to move 5 the shuttle around throughthe shed. T lie purpose of the toothed rollers on the carrier i otherparts.

is to allow the latter to get a proper hold on -the. shuttle between theinterposed warpthreads bv partin and slightly bunching or ni'assing thethrea s.

by the teeth on the wheels 28, which' latter 'rotate soos tor clearthemselves from the warp-threads and prevent inp'iry to the latter. Itwill be noted that t ie teeth of tlie 6o .wheel 28"* areratchet-like-that is, they are -rounded at the back and straight ontheir faces, as indicated in the enlarged detail View, Fig. 10. As -theshuttle advances the wheels rotate, as indicated by the arrows on thecarrier 28. The -rollers 28l are spaced'a little wider apart This resultis effected 'g enable thel harness to their outer ends thereon in thelast-named figure. The shuttle has in it a recess or aperture in whichis mounted the usual bobbin or weft-holder 32. From this holder theweft-thread is led out through a thread-eye in the shuttle. When morethan one shuttle is in play, the leading shuttle or shuttles will havemeans for elevating the weft-thread *y as it is laid, so as to ornianother shed in the warp for the shuttle following. ln Figs. 8 and 9 theshuttle is shown provided with this elevated guide 33, the elevated weftor filling thread y bein shown clearly in Fig. 9. The last or followingshuttle requires no guide 33, it being followed by the reed at itsbeating-up point, where the combined .warp or filling threads are beatup along the line z to form the tubular web or fabric W. lt need only besaid of the operation of the reed 22 that at each rotation of the shaft7 every point in the circular reed is brought up to the ine e forbeating up the warp thread or threads laid b `the shuttle or shuttles.The raceway 29 is lield firmlylin place by clips 34, so as to resist thecentrifugal force by which the rapidlyrevolving;`shuttles are thrownagainst it. A section of this raceway (indicated at 22x in Fi 2) may bemade remove able, so as to facilitate the removal of the shuttles. It isnot important what means are employed for securing this section inplace. It may be hinged to the main portion at one end,iif desired. 'lFig. 11 is a planview, detached, of the cani for operating the heddleswhen two shuttles are employed. Fig. 12 shows a cam suited for operatingthe lieddles when but one shuttlc is employed, and Fi v. 13 shows a camsuited 'for operating.,r the lie ddles when three double or figure 8"forni, and the groove therein forms four vxtronw openings or sheds inthe wiups. 'lhil am 17" of Fig. 122 for one shuttle is anniv-what morecomplex than the other two und requires the cooperation of This mun hasin its upper face two intersecting circular cam-grooves 3 5 and 36, thoformer being sinall and f concentric with the cant-shaft and the othereccentric and in allrespects like the groove in the cam I7 of Fig.4 11.The roller on the lower side of the slide 21 which engages the groove-in the cam will traverse each of the grooves 35 and 36 alternately,being' switched from one to the other at their intersectionbyineaxisseen in Fig. 12, which is a bottom orfback view 0f' the cam 17.'lliis switch device comprises a lever-like switch-tongue 37., the head37* of which extends up into the seid grooves at their intersection, aspirng 38 to hold seid tongue in one of its two positief", and a.rotating four-minted-stor com ...1, adapted, when turne a, quarter wa,round, to push over the switch-tongue en let it beek. A t

each revolution of the shaft 7 this 'ster ssrn is turned a. quarter wayround hy e suitebie stud in its ath on the loom-frame. This stud is nots own in the drawings, as the cam 1? is not used therein; but the useand application of such o stud will be obvious to any reed; but when theweft-thread one skilled in mechanics.

The loom may be driven-by en electric rno- 'tor M, (seen in Fig. 1,)theermeture of the motor being, if desired, secured on the shaft 7.'This motor may be driven from any generster G (seen in Fig. l) through acircuit C. This circuit has in it a broke controlled by an automatielining stop motion which 'isili now be deseibed with especial referenceto Figs. 1 2, an 8.

The reed 22 is electrically insulated from the other metal parts of theloom;` but the toothed wheel 29, which is of metal, makes metalliccontact with the metal vroller 31 on' the shuttle S, the bod of which isof wood or other non-metallic su stance. The iron axis or arbor (31 inFi m10) ofthe roller 31" is in metallic Contact with a metal strip 40,set in the shuttle-body, und this stri is in contact at all times with ametall dropever or hinged hail 4l on the shuttle. This bail may, if leftfree, drop onto' the metal dents of the reed 22, thus establishingelectric eontect with the bohhin is intact this thread whic takes underthe hail 4l llft-s and holds the bail out of contact with the reed, thusmaintaining a break in the operating electric oircuitof theV stopmotion.

It may: be well to explain here that the nro-'j tor-circuit C has in ita switch 42, by which it' may he broken by the weaver 'for stopping theloom, and that there is in said circuit another break at 43,held closedbyaweighted armature-lever 44. An electromagnet 45 is adopted to breakthe motor-circuit at 43 hy attracting its armature earri'ed by theweight-od lover 44. This eleetromagnct has its coil in neireuit c,eslledthe controllingcireuit, and which has in itehattery 46. Thiscontrolling-aimait is grounded in the motel loomfralne 3 nt 47 and fromthis point the current flows tu tho shuttle sind the Smil 41, and whenthis huil drops into uninet with the reed 22 the current is completedthrough the magnet ,45'nnd tho motor-oircuit isthus broken. i f
